This invention has reference to an improved construction of heatingapparatus forming a combined radiator and convector unit in which theheating medium ma be either hot water or steam, the object 0 theinvention being to produce a heating unit which not only serves for thepurpose of direct radiation, but also for indirect heating by convectionwith means to enable the convected heat to be regulated as desired, andof such construction as to prevent lodgment of dust or other matter onall interior parts and ample provision for easy cleaning.

According to this invention the unit comprises any number of thinvertical sections or heating elements, each section being constructedpreferably but not necessarily of two sheet metal plates spaced apartpreferably by a metallic marginal strip. Located between these plates isa continuous coil of metal piping through which the heat- I ing mediumcirculates, such coil being con nected to the flow and return servicepipes in the usual manner with the necessary control valves.

Transmission of heat from the coil to the plates is obtained by contactwith the plates and by embedding such coil in plaster or other suitablematerial having a high conduction coefficient which entirely fills upthe space between said plates.

The sections are assembled to form the unit, with an intervening spacebetween each for the passage of air, which air enters at the base of theunit and is heated by co vection in its passage upwards, beingdischarged through an opening or grating near the up er end of the aparatus, and in order to enable any or all 0 such airways to be shut offwhen desired a flap or equivalent arrangement is provided at the top ofsuch airways. Or each airway may have a separate regulating device.

When the unit is fixed in position one of 5 its plain surfaces isdirectly exposed to the room so that direct heat radiation is obtainedfrom such surface, but as the other plain surfaces at the rear, whichform the airways for the passage of air taken from the room or directfrom atmosphere, heat 1y understood I have appended the accom- 513,739,and in Great Britain lurch s, 1930.

such air by convection as it passes upwards into said room, we obtaindirect heat radiation as well as indirect heating by convectron, and asone or more of the airways can be closed when required the amount ofheat given off by convection can be varied without the necessity ofoperating the valves controlling the heating medium.

In order that the invention may be clearpanying drawing.

Fig. 1 is a sectional side-elevation showing the heating apparatus fixedagainst the wall beneath the Window of a room.

Fig. 2 is a broken part sectional front elevation of the apparatus shownby Fig. 1.

As illustrated at "Fig. 1 I have shown the combined radiator andconvector unit composed of two vertical heating elements or sections A,A assembled so as to leave an intervening space a. between the sections,but it must -be understood there may be only one or more than two ofthese sections if desired or found necessary.

Each of these sections is constructed of two thin sheet metal plates aa, spaced apart by the metallic marginal strip a, with the continuouscoil of metal piping a located between, through which pipe a the heatingmedium circulates, connections between the flow and return service pipesbeing provided in the usual manner with the necessary control valves.

Heat is transmitted from the coil (1 to the plates at, a by contact withsaid coil 0., and by filling the space between said plates with plastera or other suitable material having a high conduction coeflicient so asto entirely embed said coil.

The sections A, A when assembled are supported and fixed in position ina frame or enclosure B to form the unit, such frame B being providedwith an opening in the front so that the surface a of section A isdirectly exposed to the room, the interven- 9 ing space a between thesections form a passage for air which enters through the opening 6 atthe base of the unit and is discharged through the opening or grating 6near the upperend thereof. A flap valve 6' or equivalent is provided attheto of the airwaysa'soastoenableeither orth of such airways to be shutof when desired. Itwillbeseenasthesurfacea'ofsectionAisdirectlyexposedtotheroom,that direct heat radiation is obtained fromsuch surface, but as the other surfaces of the sections A, A whichconstitute the airways for the of air taken fromthe room or D directfrom atmosphere, heat such air b convection as it p upwards into sairoom, that we not only 0 tain direct heat radiation, but also indirectheating by convection, and as one or both of the a1rways a 13 can beclosed when required, the amount of heat given of by convection can bevaried without the 11v of operating the valves controlling the heatingmedium. The flap valve 6' regulating'the a of air through the airways aas we as e control valves may if esired be 0 rated automatically bymeans of a suite le arrangement of thermostatic control.

It will be seen as the whole of the parts 3 of theapparatus are flat andsmooth that it is upractically impossible for dust to accum ate on thesurfaces, and also that the apparatus is constructed to facilitateclean- 30 Wm: I claim as m invention and desire to secure by Lettersatsnt is: I

As a new article of manufacture a heating unit for incorporation as awall panel in a building structure comp a pair of imperforatesubstantially pa el flat sheet metal plates, a spacing strip betweensaid plates ad acent the edges thereof and servmg to enclose the spacebetween said plates,

0 and a continuous one piece heating coil mounted between said plateswithin the conlines of said spacing strip, said coil being 1n contactwith each of said plates throughout a portion of the length thereof,

a and a plastic heat conducting material filling the space between theconvolutions of said In testimony whereof I have signed m name to thisspecification. y M EDGAR HEBBING.
